URNEYS United States Patent 3,365,801 MAGNETIC TELESCOPIC MOUNT EdwardJ. De Simone, Jr., 3902 Avenue S, Brooklyn, N.Y. 11234 Filed Mar. 9,1966, Ser. No. 533,055 1 Claim. (Cl. 33-50) ABSTRACT OF THE DISCLOSURE Amagnetic mount for mounting a telescopic sight on a rifle or the likewhereby the rifle sight may be quickly assembled and removed forimmediate use of the rifle without the sight, which mount may bereplaced conveniently and with the assurance that the rifle sight willreoccupy the same relative position with respect to the barrel of therifle to which it had previously been set. A permanent magnet of veryhigh field intensity is used as a bonding agent between the rifle andthe telescopic sight. Sectional ring like brackets on the mount supportthe telescopic sight.

This invention relates to telescopic sight mountings and moreparticularly to magnetic telescopic mountings for rifles, firearms orthe like.

In the ordinary mounting constructions, the telescopic sight is rigidlymounted on the barrel of the firearm such as a rifle by means offastening members, such as screws, clamps or the like. Attachment bymeans of screws requires much time so that the sighting telescope mustremain permanently fixed to the rifle. In case of mounting by means ofclamps, a tight attachment of the sighting telescope on the bearings ofthe rifle is not easily achieved thus causing inaccuracies which impairaiming precision.

Often there is a need for a quick removal of the telescope sight for acloseup shot or other reason. In such fastened mountings, a quickdisassembly is diflicult if not impossible.

It is accordingly an important object of the present invention toprovide a magnetic type of telescopic sight mounting for rifles wherebythe rifle sight may be quickly assembled and removed for immediate useof the rifle without the sight, and furthermore may be replacedconveniently and with the assurance that the rifle sight will occupy thesame relative position with respect to the barrel to which it had beenpreviously set. It is proposed to use a permanent magnet of very highfield intensity as a bonding magnet between the rifle and the telescopicsight.

Another object of the invention to provide a mount for securing atelescopic sight to a firearm, such as a rifle, which may be permanentlyadjusted for windage and which relatively inexpensive to manufacture,maintain and repair.

Yet another object of the invention is to provide a mount for atelescopic sight that is of simplified construction and has a minimum ofmachined parts.

For further comprehension of the invention and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a fragmentary side elevational view of a rifle illustrating amount constructed according to the invention and shown securing 'aconventional telescopic sight to the rifle.

FIG. 2. is an exploded view of the mount.

FIG. 3 is a vertical sectional View taken on the plane of the line 3-3of FIG. 1.

FIG. 4 is vertical sectional view taken on the plane of the line 44 ofFIG. 3.

FIG. 5 is a perspective view of a modified form of permanent magnetunit.

FIG. 6 is a similar view of another modified form of permanent magnetunit.

Referring now in detail to the various views of the drawings, aconventional rifle is illustrated and is designated generally by thereference numeral 10. The rifle 10 has a conventional stock 12supporting a conventional barrel 14 having chamber ring 15.

The stock is formed with the usual recess 16 adjacent the rear thereof.

In accordance with the present invention, a mounting for a cylindricaltelescopic sight 18 is mounted on the receiver chamber 17 at the middlethereof. This mounting includes magnetizable material such as iron orsteel and has an elongated flat plate 20 with downwardly extendingcurved plate portion 22 secured by screws 24 threaded into threadedsockets in the side of the receiver 15 at the recessed portion 16 of thestock. A short upstanding stud 26 is secured to the top surface of theplate 20 adjacent each end by means of a threaded stem 28 threaded intoa threaded hole 30 formed in the plate 20.

A shallow elongated hollow casing 32 is removably seated on the mountingplate 20. The casing has a body 34 with curved upper side walls 36, flatend walls 38 and semicircular in cross section top wall 40. The bottomof the body is open with a ledge 42 extending inwardly of the end walls38 thereof at the bottom inner surface thereof forming a hollow chamber45.

Sockets 44 are formed in the outer surfaces of the ledges 42 at the endsof the body to receive the studs 26. The body is guided to properposition on the mounting plate by means of the lugs and sockets.

An elongated bar 46, square in cross-section, of permanent magneticmaterial is housed in the body 34 of the casing 32 with its top surfacesecured to the top wall 40 by bonding or other suitable manner. One poleof the bar, the North pole for example is positioned at the left handside and the South pole at the right hand side, of the housing, asviewed in FIGS. 1 and 2.

A pair of spaced telescopic sight bearing brackets assemblies 50 aredetachably carried by the body 34 of the casing 32. The bracketassemblies are of similar construction and each comprises a sectionalring body 52 composed of a lower section 54 and an upper section 56 asviewed in FIG. 2. The sections are removably fixed together by means ofaligned perforated ears 58 formed integrally thereon at the ends thereofand screws 60 extending through the aligned perforations. An integralflat plate 62 extends radially and tangentially from the bottom of eachof the lower sections 54. The plates 62 are of male dovetail formationfor insertion through spaced recesses 64 of female dovetail formation,in the top wall 40 of the body of the casing 32. The bracket assembliesmay be driven or press fitted into the recesses 64 by a suitable tool.

In operation, the axial centers of the bracket assemblies 50 aredirectly in line with the center of the sight of the barrel 14 of therifle, representing the center of the bore of the rifle, so that thetelescopic sight 18 will automatically align with the bore of the riflein exactly the same way each time it is placed in position in thebracket assemblies.

With the magnetic bar 46 magnetized to saturation, the tractive effortexerted on the mounting plate 20 is suflicient to hold the telescopesight rigidly with its mount in place during usage, but may be willfullyremoved from the rifle by gripping the telescopic sight 18 and liftingwith a strong vertical force the casing 32 off of the studs 26.

In FIGS. 6 and 7 modified forms of magnetic bars 46' and 46",respectively, are shown for use with the mounting plate 20 of FIG. 1.Bar 46' is of the sandwich bonded type and elongated plates 66 ofpermanent magnetizable material with plate 68 of ceramic materialtherebetween. Bar 46" comprises an elongated bar body composed ofalternating magnetizable iron or steel plates 7%) and ceramic plates 72.The ceramic plates are approximately three times thicker than the ironor steel plates.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and that various changes andmodifications may be made within the scope of the invention as definedin the appended claim.

What is claimed is:

1. A telescopic mounting of the kind described comprising an elongatedflat plate, a plate depending from said plate formed integrally with oneside edge of said fiat plate, one surface of said depending plate beingcurved, said depending plate having spaced holes therein to receivescrews for attachment to a firearm, an elongated magnetic bar removablyseated on said flat plate, an elongated hollow casing enclosing saidmagnetic bar, said casing having flat side walls, a curved top Wall,fiat end walls and being open at the bottom, the bottom edges of theside and end walls being flat for seating on the flat bar, means forremovably attaching the casing to the flat plate including upstandingstuds on the ends of the flat bar and sockets in the ends of the casingon the bottom thereof coacting with the studs, the top wall of thecasing having dovetail recesses in the top surface thereof, a pair ofring-shaped sectional brackets removably mounted in said dovetailrecesses for removably supporting a cylindrical telescopic sight, themounting for the brackets including plates extending laterally andtangentially thereof, said latter plates being of dovetail shape incross-section.
